Maintaining Units

162 3ware SATA+SAS RAID Controller Card Software User Guide, Version 10.0

If rebuild scheduling is not enabled on the Scheduling page, the rebuild

process begins almost immediately in the background. If rebuild

scheduling is enabled, the unit will not start actively rebuilding until the

next scheduled time.

Rebuilding Units through 3BM

When a RAID unit becomes degraded, it is marked as such, and the drive(s)

that failed are marked as

Not In Use in the 3BM screens.

Figure 68 shows an example of how a degraded RAID 5 unit appears in 3BM.

Figure 68. Degraded RAID 5 Array to be Rebuilt

You can start the rebuild of a degraded unit manually in 3BM, or you can let

the system boot and allow the rebuild to take place automatically.

The rebuild process will take less time if Rapid RAID Recovery has been

enabled during unit creation. See “Rapid RAID Recovery” on page 121

To start the rebuild of a unit through 3BM

1 Reboot the system and start 3BM.

A red message box informs you that the unit is degraded, and suggests

some possible approaches. Figure 69 shows an example of a degraded-

array message.

Note: If you need to cancel a rebuild, you can do so by using the Remove Drive

link on the Maintenance page to remove the drive from the unit.
